In a breakthrough study, researchers have developed a new sampling technique to help ensure the safety of infant formula. The technique, known as stratified sampling, is the first of its kind and has the potential to revolutionize food safety testing. Stratified sampling involves taking a sample of an entire population and dividing it into subgroups or “strata”. Each subgroup is then sampled independently, allowing for more accurate and efficient testing of the product. This new sampling technique could help to ensure that infant formula and other food products are safe for consumption. By providing an efficient way to test for safety, stratified sampling can ensure that only safe and uncontaminated food is reaching consumers.
